IMPROVEMENT IN MECHANICAL DEVICES.

Specification forming part of Letters Patent No. 168,645, dated October11, 1875 application filed August 18, 1875.

To all whom it may concern:

Be it known that I, J OsEPH F. KELLEY, a resident of Washington city,District of Golumbia, have invented a new and Improved MechanicalDevice; and I do hereby declare the following to be an exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making a part of thisspecification, in which-.

Figure 1 represents a front view of the machine or mechanical device;Fig. 2, a rear view; Fig. 3, a side elevation; Fig. 4, a detail view ofthe devices for gearing and ungearing the machinery from the fly-wheelat any time required. Fig. 5 represents the toggle-levers, two or more;and Fig. 6 shows the shape of such toggle-levers.

The nature of my invention consists in the arrangement and combinationof the weighted guide-rods, incline planes, toggle-levers, and fly-wheelgearing, as hereinafter described.

The object of my invention is to apply this mechanical device tostreet-cars, vessels, and machinery. 7

A represents the square upright frame; B, the horizontal floor-frame orplatform; (J O, the weights, as shown at Fig. 1; D D, the upper andlower incline planes and frictionrollers F F, operating the levers E E.G G are the cog-wheels that engage rack-bar J alternately on each sideof the center vertical shaft H. The toggle-levers E E expand andcontract during their movement. Each lever E (therebeing two or more)has a slot, M, at each end, that makes it adjustable upon the journal ofthe friction-roller F. The wheel Gr may be operated by a crank on theend of its axle, by hand or any other power. The center vertical shaft Hrevolves with the incline planes D D, and the bevel-gearing Y Ytransmits motion to gearing on the car-wheel axle below, as shown atFigs. 1 and 3. The weights 0 0 move up and down alternately with theirguide-rods and friction-rollers,which rise and descend upon the inclineplanes D D. The fiy-wheel P operates horizontally; it is located uponone end of the shaft It, and the bevel-wheel S is at the other end ofthe shaft 1t. The bevel-wheel T is movable upon the horizontal shaft U,and is geared into or ungeared with the bevel-Wheel N of shaft H byshifting the bevel'wheel T backward or forward by means of thehorizontal lever V, and the horizontal lever W gears or nngears thebevel-wheel X with the bevel-wheel S, by which means the wheel G isstopped, as also that of the levers E. The fly-wheel P regulates themotion of shafts B, U, and H, and by this arrangement all the machinerycan be easily geared or ungeared from the flywheel shaft, thongh underfull speed the motion of the machinery will be retarded 0r checked,while the fly-wheel continues its rapid revolution for some minutes,when, by again gearing the bevel-wheels N, S, and T, the force of therevolving fly-wheel instantly starts and hastens the progress of themachine.

What I claim as my invention, and desire to secure by Letters Patent, is

The vertical shaft H, with its incline planes D l), friction-rollers FF, weights 0 O, togglelevers E E, rack J, cog-wheel G, bevel-gearin g N,S, T, and Y, and fly-wheel P, all arranged, combined, and operating asherein described, and for the purposes set forth. 7
